One thing I dislike about too many martial arts books is how much they focus on...well...martial arts. The truth is, details of technique for punching, kicking, stabbing, shooting, choking, and avoiding all of those things when they're aimed at you are the least important aspects of self-defense.
David Kahn is one of the world's leading experts on the martial art Krav Maga, which has a somewhat deserved reputation of being one of the worst offenders in that category....but David, and his new book recently published by YMAA, are different. My conversation with David included a little bit of martial arts geekery, but focused mainly on the techniques, mindset, and knowledge we need as parents to avoid ever having to use martial arts. Which is what the goal should be in the first place.
